Intelligent fiber, fabric not only mechanical property and electric conductivity with higher, but also photo-thermal, electric heating and mechanics sensitivities may be implemented
Can, there is very big application potential in wearable product scope, belong to Material Field.
Background technique
Fibrous material has other excellent performances such as good mechanical property, anisotropy, increasingly by people's
Concern, is with a wide range of applications.In recent years, more and more researchers be dedicated to studying fiber with high performance or
Fabric.Such as nano-cellulose can be carried out the macroscopic fibres that one-dimensional assembling preparation has strong mechanical property by microfluid spin processes,
And with polymorphic, hierarchical structure regenerated silk fiber etc..But current natural fiber or synthetic fibers only have mostly
Single function, and be all much electrical isolation or thermal insulation, limit their application range.Therefore, it designs and prepares
It, will be with important scientific meaning and practical application value with multi-functional intelligent fiber and textile material.
MXenes is that one kind by the Yury Gogotsi professor of Univ Drexel, the U.S. et al. discovery in 2011 is novel
Two dimension (2D) transition metal carbide or carbonitride.Its chemical general formula can use Mn+1XnTxIt indicates, wherein M refers to transition group gold
Belong to, X refers to that C or/and N, n are generally 1-3, TxRefer to surface group (such as-F ,=O ,-OH etc.).Currently, MXenes is due to having big
It the features such as specific surface area, excellent electricity/thermal conductivity, has been shown in fields such as conductive filler, absorption, sensor, energy storage huge
Big potentiality.However, the interaction force between 2D type MXenes nanometer sheet is small, it is difficult to independently form macroscopical 1D structure, limits
Its application value.
